Suppose you invest 1600 at annual interest rate of 7.9% compounded cont how much will u have after 10yrs

frez [133]

Answer:

B. $3525.43

Step-by-step explanation:

We will use continuously compound interest formula to solve our problem.

$A=P*e^{rT}$

A= Amount after T years.

P= Principal amount.

r= Interest rate (in decimal form).

e= The mathematical constant e.

T= Time in years.

First of all we will convert our interest rate in decimal form.

$7.9\text{ Percent}=\frac{7.9}{100}=0.079$

Now let us substitute our given values in above formula.

$A=1600*e^{0.079*10}$

$A=1600*e^{0.79}$

$A=1600*2.2033964262559365$

$A=3525.4342820094984\approx 3525.43$

Therefore, we will get an amount of $3525.43 after 10 years and option B is the correct choice.

A city's population is currently 500,000. If the population doubles every 65 years, what will the population be 130 years from n

kompoz [17]

Answer:

2,000,000

Step-by-step explanation:

Simple maths, really.

65 times 2 is 130, and the population is already 500,000 with no time passing. 65 years later, the population would be 1,000,000. 65 years after that, the population would double again, so the answer would be 2 million.

Hope this helped!

Solve the triangle. Round your answers to the nearest tenth.

wel

Answer:

m∠A ≈ 43°

m∠B ≈ 55°

mBC ≈ 20

Step-by-step explanation:

Law of Sines: $\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Step 1: Find m∠B

$\frac{29}{sin82} =\frac{24}{sinB}$

Step 2: Solve for ∠B

29sinB = 24sin82°

sinB = 24sin82°/29

B = sin⁻¹(24sin82°/29)

B = 55.038°

Step 3: Find m∠A

180 - (55.038 + 82)

180 - 137.038

m∠A = 42.962°

Step 4: Find BC

$\frac{29}{sin82} =\frac{BC}{sin42.962}$

Step 5: Solve for BC

29sin42.962° = BCsin82°

BC = 29sin42.962°/sin82°

BC = 19.9581
